ObjectiveTo study the effect of valgus malalignment on knee osteoarthritis (OA) incidence and progression.
MethodsWe measured the mechanical axis from long limb radiographs from the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI) to define limbs with valgus malalignment (mechanical axis of ≥1.1° valgus) and examined the effect of valgus alignment versus neutral alignment...
The objective of the study was to evaluate the reliability of frontal plane lower limb alignment measures using a landmark-based method by (1) comparing inter- and intra-reader reliability between measurements of alignment obtained manually with those using a computer program, and (2) determining inter- and intra-reader reliability of computer-assisted alignment measures from full-limb radiographs...
Measurements of elongations of the cruciate ligaments have been used to study the behaviors of these ligaments in-vitro and in-vivo, mostly based on simplified two-bundle models of the cruciates. The complex fiber anatomy of the cruciates may suggest a complex deformation behavior across the continuum of their substance that cannot be captured by only two measurement points. In this study, a new methodology...
The function of the replaced knee joint is influenced by many factors, including implant design, material properties, fixation and surgical techniques. General surgical approaches have changed in tandem with design developments, but within them various technical elements of knee surgery are strongly adhered to (conservation) whilst others are vigorously debated (variation). The merits of debate...
